Each role has a set of permissions assigned to it, and these permissions indicate which actions a user in that role can perform. For each role, you can only grant permissions; you cannot specifically deny a permission. A user's permission set consists of all granted permissions for all roles that the user belongs to.

To assign or review permissions for a role, click the Roles link.

Click Edit for the role you want to modify or review.

By default, Orchard includes a number of roles with default permissions:

Administrator - Can perform any operation (has all permissions)

Editor - Can author, publish and edit his own and others' content items.

Contributor - Can author and edit his own content items, but not publish them (save draft only)

Anonymous - Can view the front-end of the site only.

Authenticated - Can view the site front-end, and perform other operations depending on the site and other role permission settings.

Implied Permissions

Some permissions specify whether a user is allowed to perform a single action; other permissions specify whether the user is allowed to perform a group of actions. The permissions that pertain to a group of actions are typically higher-level permissions that logically include lower-level actions. When you grant a higher-level permission that relates to a group of actions, the lower-level permissions are implicitly included. For example, if you grant a role permission to manage blogs, you are also granting that role permission to edit, publish, and delete blogs.

You can see which permissions are explicitly or implicitly granted by examining the check boxes in the Allow and Effective columns. The Allow column shows which permissions are explicitly granted and the Effective column indicates which permissions are explicitly or implicitly granted. The following image shows that Manage blogs was specifically granted to the role and the other permissions were implicitly granted.

If you unselect the Manage blogs permission, all of the other permissions are also revoked.

The following image shows a role with Edit any blog posts granted. Edit own blog posts is implicitly granted.

The following image shows a role with only Edit own blog posts granted. No permissions are implicitly granted with this selection.
